I have nothing bad to say about PPG. I really don't recommend a particular paint. The name brand ones that you really pay for are really going to give you the same results (Except maybe Shirley Wilson -I can't recommend them) given you do good prep and other factors don't come in. I have used DuPont (now named Axalta but the same chemically) PPG, Spies-Hecker for ages and all do pretty much the same thing. I love Glasruit, but most people can't get the hang of it because it takes a long time to get used to. It will resist fuels really well so I like it for boats and Jet Skis. If you're new to this, get the hang of it on auction cars or something you can afford to screw up. Possibly buy the cheap stuff if you aren't experienced too. Paying thousands for materials that may end in not very good results may not make sense if you're new to this. With the name brands you are paying for a warranty and racing teams. You actually get neither. The warranty is for shops that are in their contracts like big collision shops. The big paint companies meet every year outside of the US and compare next years price increases. They don't do this on US soil, so it isn't price fixing. You'll notice they all increase their prices by the same rate, so even if you switch, the increase is the same. If you are in a contract, you probably can't switch anyway. I just mention this because when you go to price materials, you will probably get some serious sticker shock.
